Self-compassion can be a useful tool for success.
A lawyer I once worked with had just managed a deal that went dreadfully wrong, one in which his client was left unsatisfied and his managing partner was, well, unhappy to say the least.
This lawyer lamented his shortcomings and was finding it difficult to move on. Subsequently his next deal was painfully difficult. Though successful by most objective measures, he found it difficult to see the positives. It is fair to stay he was frozen by his fear of failure. Over time, he became emotionally depleted and concerned for his capacity to continue working in the profession he was once so passionate about.
